To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil for a 2-year period.
To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil for a 2-year period. The maximum penetration (in mils) for each specimen is then measured, yielding a sample average penetration of x̅ = 52.8 and a sample standard deviation of s = 4.9. The conduits were manufactured with the specification that true average penetration be at most 50 mils. They will be used unless it can be demonstrated conclusively that the specification has not been met, what would you conclude? (Use α=0.05.)
State the appropriate null and alternative hypotheses.
Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.)

To obtain information on the corrosion-resistance properties of
a certain type of steel conduit, 25 specimens are buried in soil
for a 2-year period. The maximum penetration (in mils) for each
specimen is then measured, yielding a sample average penetration of
x ̄ = 52.7. According to the normal probability plot, we can
observe a linear pattern using the sample we have. The conduits
were manufactured with the specification that true average
penetration be at most 50 mils. They will...

case study
SV is a 45 year old woman who was diagnosed with type 2
Diabetes 5 years ago. She has not been back to her doctor since
then. She decided to return at this time because of chronic fatigue
and blurry vision. Her A1c level is 8.3%, Triglycerides are
275mg/dL. Her height is 5’4” and her body weight is 175# (BMI is
30). She states that she hasn’t returned for any follow-up visits
because the only advice she gets...
